Good advice, really, thanks Malcolm!
so far I could come up with a workable code,
I will have to improvise more, obviously
I'll have to figure out a way to use that "for loop" in the case of
"salary" variable. I'm just using an example from 1 to 5 to ilustrate
a
possible shortcut to get to the issue.
#include <stdio.h>
#include <ctype.h>
void readPerson (char *first, char *last,
int *age, int *ssn, float *salary) {
printf("First name: ");
gets(first);
printf("Last Name: ");
gets(last);
printf("Age: ");
scanf("%d", age);
printf("Social security number (no hyphens, just 3 figures): ");
scanf("%d", ssn);
printf("Salary: ");
scanf("%f", salary);
}
/* This writes out information about a person. */
void writePerson (char *first, char *last,
int age, int ssn, float salary) {
printf("%s %s, %d years old, SSN %d, salary of $%9.2f\n",
first, last, age, ssn, salary);
}
int main(void)
{
int i;
FILE *fp, *fs;
fs =3D fopen("ak4.bin", "wb");
for (i =3D 0; i < 5; i++) {
fputc(i, fs);
}
fclose(fs);
fs =3D fopen("ak4.bin", "rb");
fp =3D fopen("ak5.txt", "w");
while ((i =3D fgetc(fs)) !=3D EOF) {
printf("%d\n", i);
fprintf(fp, "%c", isprint(i) ? i : '.');
fprintf(fp, " %d\n", i);
}
{
char first[100];
char last[100];
int age;
int ssn;
float salary;
readPerson(first, last, &age, &ssn, &salary);
writePerson(first, last, age, ssn, salary);
}
}
